From my experiences with removing the fan filter; is that NO traffic was affected.  Be careful cleaning the filters, the ones we have are a foam type that really don't allow for cleaning, just replacement. ... View more

You might want to check the PRI protocol type in case the 2 Telco's use different switches.  Lucent vs. Nortel.  ... View more

Thank you Dan, we don't have any PSTN SIP trunks that we have to worry about blocking anonymous calls.  We are using just the very basic call blocking you describe in the call flow above.  We moved our MCGP trunks to the new cluster, which were built by hand, not imported or migrated from the other cluster.  They were built just like the other cluster.  We're 65% through a migration, and we have 95% of our end devices sitting on our 8.6 cluster.  The 2 clusters are tied together with a SIP trunk.  Incoming calls will come in the PRI's and most calls will flow across the SIP to the 8.6 cluster.  Some calls will flow to end devices on the 10.5 cluster.  I'm pretty new to Call Manager, but not telephony and voice switching, so I'm having a difficult time trying to "translate" between the 2.  So I apologize if I sound green, it's because I am.  I'm pretty sure my problem lies in a CSS/Partition snafu somewhere between the SIP/PRI/Phones on the 10.5 cluster.      ...

Do you know of any changes to this process in the later 10.5 release?     We are migrating from a appliance based 8.6 system over to a brand new virtual 10.5 system.  The 10.5 system is a ground up built cluster that we are migrating over to.  We had call blocking working just fine on our 8.6 system, with the instructions listed above.  But when we tried to implement this same process on the new 10.5 cluster it doesn't work.   It will block any call coming down that particular MCGP gateway PRI.  We have about 16 PRI's to apply this call blocking CSS on, but I can't get it working right yet.  I'm just working on 1 PRI as to not kill all incoming calls into my system.   Thank you,   Mat ...

I had the same problem. It seems to be an issue when importing CSS's with different numbers of partions assigned to them.  I was able to import CSS's into our 10.0.1 release by importing all CSS with 22 partions, then importing the CSS's with 21 partions and so on.   It was a huge pain, and I think there must be some kind of bug in there. ...

No dice...  I reset the active TCC2P card, waited for the switchover and the card to reload, with zero luck in opening an IOS connection.  I get the original message reported above.  Obviously no one can be in it when I reset the TCC card... I also reset the ML card and tried opening IOS then, and again, same message. Any other ideas?  Probably going to be opening a case on this on... ... View more

What a week!  I will be getting approval to reset the TCC and ML cards this Wednesday evening.  I will report back here with what I discover the following day.  Thank you. ... View more

Gotcha, thanks.  I have uploaded a backup of one of the nodes.  I will need to wait until my maintenance window to try the TCC reset followed by the ML card reset. ... View more

Thank you for the quick reply Sunil. I was consoled directly into the card via my PC/serial connection.  My security folks block Telnet on our network. I do have a quite a few logins throughout the ring, but they are just using CTC in the node/network view and not using IOS.  It is my NOC that is monitoring the TDM side of the ring.  When you say post a database, are you meaning a backup of the node?
